It means you're going to need to work much harder to catch up with Jon Skeet.

Not much. I think counting users with 1 rep shouldn't be counted in the stats.

@Will are ALL users counted? I thought <200 rep users were not tracked in the leagues?

@giddy leagues are one thing, your percentage as reported on your profile is another. Seems like people with 100 rep are still in the top 10%, which suggests to me they're counting all users in that.

The amount of reputation you've gained in this week puts you within the top 15% of reputation gained as compared to other users for this week. If I'm not mistaken it's also a rolling percentage. If you gain even more today you might be in the top 12% this week tomorrow, or in the top 17% if you don't gain any/gain as much.

If you also navigate to the Users page on stackoverflow you will see something similar. (Your daily and weekly rep gain is also displayed on the drop down view when you hover on the down pointer on your username on the top.)
